Videos posted on social media show large crowds of protesters marching through Tehran and other Iranian cities, highlighting what is described as the largest displays of opposition against the clerical establishment in years. In some parts, peaceful demonstrations proceeded without intervention from security forces, while in other areas, violent clashes erupted. Protesters in Mashhad openly called for the overthrow of Supreme Leader Ayatollah Ali Khamenei and the return of Reza Pahlavi, the exiled son of the former shah. The protests, which are now entering their twelfth consecutive day, have reportedly spread to over 140 cities and towns across all 31 provinces in the country, with significant arrests and casualties documented. Escalating economic troubles, especially a drastic drop in the value of the currency and soaring inflation, are fueling public outrage and unrest in this turbulent period for Iran.
